Technical Field
[0001] This utility model relates to the field of fire sprinkler head technology, and in particular to a damage-resistant sprinkler head for fire protection engineering. Background Technology
[0002] Fire sprinkler heads are used in fire sprinkler systems. They are water spraying devices that automatically activate within a predetermined temperature range under the influence of heat, or are activated by control equipment according to a fire signal, and spray water according to the designed spray pattern and flow rate. Fire protection engineering anti-damage sprinkler heads are sprinkler heads designed to reduce water splashing and prevent damage in the event of a fire.
[0003] When the smoke from a fire is dense or the fire is large, the splash guard may not be able to spray water evenly to the entire protected area, resulting in some areas not being effectively extinguished. Therefore, it is necessary to provide a sprinkler head that can spray water evenly to improve the reliability of fire extinguishing. Utility Model Content
[0004] The purpose of this utility model is to provide a damage-resistant sprinkler head for fire protection engineering, in order to solve the problem mentioned in the background art that when the smoke generated by a fire is dense or the fire is large, the splash plate may not be able to spray water evenly to the entire protected area, resulting in some areas not being effectively extinguished.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a damage-resistant sprinkler head for fire protection engineering, comprising:
[0007] A spray assembly, comprising a heat-sensitive element and a splash plate, the splash plate being fixed to the bottom end of the heat-sensitive element;
[0008] The diversion assembly includes a rotating plate, a movable groove, a movable rod, a baffle, and a diversion plate. The rotating plate is located below the splash plate. The movable groove is opened in the middle of the outer side of the rotating plate. The movable rod passes through the inside of the movable groove. The baffle is fixed to one side of the movable rod. The diversion plate is fixed to the middle of one side of the movable rod.
[0009] Furthermore, the spray assembly also includes a threaded pipe and a mounting plate, the mounting plate being fixed to the bottom surface of the threaded pipe, and the heat-sensitive element being fixed to the center of the lower surface of the mounting plate.
[0010] Furthermore, the diversion assembly also includes a mounting frame, a motor, and a connecting shaft. The mounting frame is fixed to the center of the lower surface of the splash plate, the motor is fixedly installed inside the mounting frame, and the connecting shaft is fixed to the output end of the motor.
[0011] Furthermore, the inner diameter of the movable groove is large, the outer diameter is small, and the movable rod reciprocates horizontally within the movable groove.
[0012] Furthermore, it also includes a reinforcement component, which includes a mounting groove, a reinforcement rod, a fixing hole, a spring, and a locking pin. The mounting groove is opened at the center of both sides of the mounting plate, the reinforcement rod passes through the inside of the mounting groove, the fixing hole is opened at the upper outer end of the reinforcement rod, the spring is fixed inside the fixing hole, and the locking pin is fixed at one end of the spring.
[0013] Furthermore, a connecting plate is fixed to the bottom surface of the reinforcing rod, and the mounting groove is inverted U-shape, with the upper surface of the connecting plate in contact with the lower surface of the mounting plate, and a chamfer is provided on one outer end of the locking post.
[0014] Compared with existing technologies, the advantages of this utility model are:
[0015] I. This utility model, through the setting of a spray assembly and a diversion assembly, when the spray head is spraying, the heat-sensitive element bursts, causing the blockage on the lower surface of the threaded pipe to fall off. At this time, the water is sprayed out, passes through the splash plate, and falls onto the upper surface of the rotating plate. At this time, through the external controller, the controller starts the motor, the motor drives the connecting shaft to rotate, and the connecting shaft synchronously drives the rotating plate to rotate. Under the rotational force, the movable rod moves outward inside the movable groove, and the baffle blocks the inside and outside of the movable groove, causing the diversion plate to move outward. At the same time, the diversion plate also rotates, evenly diverting the sprayed water to a longer distance, increasing the spray distance of the spray head. The design of the rotating plate and the diversion plate allows the water flow to cover the protected area more widely, improving the fire extinguishing efficiency.
[0016] II. Based on the first beneficial effect, the reinforced components, when screwing the threaded pipe onto the fire sprinkler pipe, allow workers to push the reinforcing rod upwards, inserting its upper end into the ceiling. When the clamping post contacts the lower surface of the ceiling, the spring compresses inside the fixing hole. When the top of the reinforcing rod is fully submerged in the ceiling, the spring quickly returns to its original shape, causing the clamping post to move outwards and engage with the upper surface of the ceiling, thus reinforcing the sprinkler head again. The upward pushing of the reinforcing rod and the compression deformation of the spring not only improve the installation stability and structural strength of the fire sprinkler head but also facilitate maintenance and adjustment, extend its service life, and enhance safety.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0030] Please see Figures 1 to 4 As shown, this embodiment is a damage-resistant sprinkler head for fire protection engineering, comprising:
[0031] The spray assembly includes a heat-sensitive element 13 and a splash plate 14. The splash plate 14 is fixed to the bottom of the heat-sensitive element 13. The spray assembly also includes a threaded pipe 11 and a mounting plate 12. The mounting plate 12 is fixed to the bottom surface of the threaded pipe 11, and the heat-sensitive element 13 is fixed to the center of the lower surface of the mounting plate 12.
[0032] The heat-sensitive element 13 is one of the core components of the sprinkler head. It is very sensitive to temperature changes. When the ambient temperature reaches its set value, the heat-sensitive element 13 will burst or deform, thereby triggering the sprinkler head's activation mechanism. The splash plate 14 is used to evenly disperse the water flow and increase the fire extinguishing effect.
[0033] The diversion assembly includes a rotating plate 24, a movable groove 25, a movable rod 26, a baffle 27, and a diversion plate 28. The rotating plate 24 is located below the splash plate 14. The movable groove 25 is opened in the middle of the outer side of the rotating plate 24. The movable rod 26 passes through the inside of the movable groove 25. The baffle 27 is fixed to one side of the movable rod 26. The diversion plate 28 is fixed to the middle of one side of the movable rod 26.
[0034] The rotating plate 24 is one of the core components of the diversion assembly. It rotates by the drive of the motor 22 to divert the water flow. The movable slot 25 is used to accommodate the movable rod 26, and the diversion plate 28 is used to guide the water flow, which can achieve uniform distribution of water flow and a longer spray distance.
[0035] The diversion assembly also includes a mounting frame 21, a motor 22, and a connecting shaft 23. The mounting frame 21 is fixed to the center of the lower surface of the splash plate 14. The motor 22 is fixedly installed inside the mounting frame 21. The connecting shaft 23 is fixed to the output end of the motor 22. The inner diameter of the movable groove 25 is large, and the outer diameter is small. The movable rod 26 reciprocates horizontally within the movable groove 25.
[0036] Working principle:
[0037] When the spray head is spraying, the heat-sensitive element 13 bursts, causing the blockage on the lower surface of the threaded pipe 11 to fall off. At this time, water is sprayed out, passes through the splash plate 14, and falls onto the upper surface of the rotating plate 24. At this time, the external controller starts the motor 22, which drives the connecting shaft 23 to rotate. The connecting shaft 23 synchronously drives the rotating plate 24 to rotate. Under the rotational force, the movable rod 26 moves outward inside the movable groove 25. The baffle 27 blocks the inside and outside of the movable groove 25, causing the diverter plate 28 to move outward. At the same time, the diverter plate 28 also rotates, evenly diverting the sprayed water to a farther distance and increasing the spraying distance of the spray head.
[0038] In this step, the design of the rotating plate 24 and the diversion plate 28 allows the water flow to cover the protected area more extensively, improving fire extinguishing efficiency.
[0039] Please see Figures 1 to 4 As shown; this embodiment, based on embodiment 1 above, further includes:
[0040] The reinforcement assembly includes a mounting groove 31, a reinforcing rod 32, a fixing hole 34, a spring 35, and a locking post 36. The mounting groove 31 is opened at the center of both sides of the mounting plate 12. The reinforcing rod 32 passes through the inside of the mounting groove 31. The fixing hole 34 is opened at the upper outer end of the reinforcing rod 32. The spring 35 is fixed inside the fixing hole 34. The locking post 36 is fixed to one end of the spring 35. A connecting plate 33 is fixed to the bottom surface of the reinforcing rod 32. The mounting groove 31 is inverted U-shaped. The upper surface of the connecting plate 33 contacts the lower surface of the mounting plate 12. A chamfer is opened at one outer end of the locking post 36.
[0041] The mounting slot 31 is used to accommodate the reinforcing rod 32, and the fixing hole 34 is used to install the spring 35. When the reinforcing rod 32 is subjected to an upward thrust, the spring 35 will be compressed; when the thrust disappears, the spring 35 will return to its original shape, thereby providing additional stability.
[0042] Working principle:
[0043] When the threaded pipe 11 is screwed onto the fire pipe, the worker then pushes the reinforcing rod 32 upward so that the upper end of the reinforcing rod 32 is inserted into the ceiling. When the clamping post 36 contacts the lower surface of the ceiling, the spring 35 is compressed inside the fixing hole 34. When the top of the reinforcing rod 32 is inserted into the ceiling, the spring 35 will quickly return to its original shape, and the clamping post 36 will move outward so that the clamping post 36 is locked with the upper surface of the ceiling, thus reinforcing the sprinkler head again.
[0044] This step, where the upward pushing of the reinforcing rod 32 and the compression deformation of the spring 35 not only improves the installation stability and structural strength of the fire sprinkler head, but also facilitates maintenance and adjustment, extends its service life, and enhances safety.
